CAR-AXLE Specification of'Letters Patent.

Patented Oct. 15, 1907'.

Application tiled May 4, 1907. Serial No. 371,868.

To all 'whom 'it may concern:

lc it known that l'-` LANGLEY HALL, a citizen of the United States, residing at Astoria, in the county of Glatsop and State ol' Oregon, have invented a new and nscl'ul (laruexle, of which the following is-a 'specification.

This invention relates to lubricating axles for railway trucks, cars and other rolling stock and has `for its object to provide a sectional axle in which the axle sect ions are free to revolve independently oi' each other th'creby to prevent undue iriction on the car wheels when traveling around curves.

A lurlher objectief the invention is to provide means for lubricating the axle sections, and means for limiting the longitudinal movenient ot' said sections.

A still further object of the invention is to generally improve this class ol devices so as to increase their utility7 durability and efficiency. l i

Further objects and advantages will appear inthe iollowing description, it being understood that various changes in Ylol-n1, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specilication: Figure `l is a front elevation of a sectional car axle constructed in accordance with my invention. Fig. 2 Vis a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view taken on the line BMS ol' Fig. l. Fig. 4 is a side elevation of the inner section ol'ethe axle detached.

Similar numerals ol reference indicate corresponding parts in all oi the gures'of the drawings.

The improved axle forming the subject mattei' of the present invention is preferably constructed in two sections 5 and (i, the outer section 5 being formed with a tapering longitudinal bore or socket 7 lor the reception of the correspondingly tapered end 8 of the axle, as shown. The outer section 5 is provided with an annular [lange 9 which extends laterally from the exterior wall of said section, and spaced from said flange and loosely mounted on the inner section 6 of the axle isa collar 10 provided with a similar' flange 11, said flanges being spaced apart by an intermediate band or ring 12 thereby to torni Aa chamber 13 for the reception of a quantity of oil or other lubricant. The flanges 9 and 11 are formed with annular seating recesses 14 adapted to receive the band'or ring 12, there being alined openings 15 formed in the flanges for the reception of bolts or similar fastening devices 1G which extend trans-d versely through the chamber 13 for engagement with` clamping nuts 17, as shown.

As a means for feeding the oil or other lubricant from the chamber 13 to the socket 7 the tapering end of the inner axle section is formed with 'a longitudinal groove or channel 18, there being an air-vent or opening 19 formed in the end of the outer axle section 5 and communicating with the groove 18, thereby to permit the oil to How from the chamber into said groove.

The oil or other lubricant is introduced into the chamber 13 through a feed opening 20, the latter being normally closed by a pivoted lid or cap-piece 21 having an opening `formed in one end thereof for the reception of an eye or staple 22 carried by the band 1.2 and which receives a key or Cotter-pin 23 so .as to efectually retain the cap 2l in closed position.

Asa means for preventing longitudinal movement of the axle sections,vthe inner section 6 is ormed with an annular collar or shoulder 24 which is preferably spaced inwardly from the walls of the chamber' 13 so that the fastening devices 1G may be adjusted to clamp the ring 12 between the flanges 9 and 11 without effecting the collar. l

It will thus be seen that when oil or other lubricant is introduced into the`cha1nber 13 the latter will How through the groove 18 and thus thoroughly lubricate the axle sections, the latter at the same time being eiectually housed and protected so as to prevent the entrance of sand and dust to the bearing. -l From the foregoing description it will be seen that there is provided an extremely simple, inexpensive and efficient device admirably adapted for the attainvment of the ends in view.

Having thus described the invention what is claimed is:

1. An axle including telescopic sections one of which is provided with an annular flange and having a vent openim,r formed in one end thereof, a collar loosely mounted on the adjacent section and provided with a similar flange, a band interposedvbetwcen the flanges and formingl an oil chamber, fastening devices extending through said flanges,

and a collar secured to the inner section and disposed hctween said flanges, there being a longitudinal groove formed in the inner axle and vcommunicating with the air vent.

2. ln axle including telescopic sections one of which is provided with an annular flange, a collar loosely mounted on the adjacent section and provided with a similar' flange, there being seating recesses formed in said flanges, a band engaging the seating recesses and forming an oil chamber between the saine, clamping 'devices extending, throng-h the anges for locking the band in the seatingl recesses, and a collar 'rigidly secured to the inner section and extending between the walls of the oil chamber at said flanges.

3. Au axle including telescopic sections one of which is provided with an annular ange, :L collar loosely mounted on the opposite section and provided with a similar flange spaced from the adjacent ange to forni an intermediate oil chamber, a baud interposed between said flanges, and having a feed opening formed therein, clamping devices extending through the flanges for locking the band in position, and zi closure for the feed opening, there being an air-vent formed in one end of the outer member and a longitudinal lubricating groove formed in the Ainner member and communicating' with the air-vent and lubricating 10 chamber, respectively.

In testimony that I claim the foregoing :is my own, I have hereto atlixed my signature in the presence of two witnesses. v

LANGLEY HALL.
